Chances Are Your Brake Rotors Are Warped. Does The Shaking Sensation Have More Space Between Each 'Shake' As Your Speed Decreases?

If So Its Almost Guaranteed Warped Rotors. I Would Suggest You Get A New Set Of OEM Rotors And Stop Using Light Brake Pressure. Brakes Are Used to Slow A Car Down Or Stop A Car, NOT To Maintain Speed. You Should Never Need To Use Your Brakes On The Freeway And Dont Have Your Foot On The Brake For More Then 10 Seconds If You Can Help It. That Includes Going Down Hill. Try To Use A Lower Gear Instead Of constant Brake Pressure To Maintain Speed.
